Hey guys, I guess I'd be considered a big newb, and I have a weird problem I'm hoping to get some feedback on, because Sony CS is supremely unhelpful. I have a brand new STR-DN840, and I have my cable box and blu-ray player hooked up by HDMI, and then I have output going to my TV via HDMI as well. The sound is fine (as far as my ear can tell), but when I first turn on the receiver after it has been off for a while and switch to the cable or blu-ray player, often there is a problem with the picture. Forgive me for not being able to describe it very well, but the picture looks scratchy, kind of like if an old analog tv signal wasn't coming in very clear. Sort of. This problem actually resolves itself pretty quickly (within a minute or 2) without me doing anything, but there is a second problem that doesn't go away quite so easily. The color is off. It's darker, and sort of greenish sometimes. This problem is fixed after I cycle the receiver on and off several times, but it's driving me crazy. What in the world could be going on in there?
